Problems solved by technology

At this time, when sending bit 1 or bit 0, there must be a bit represented by a low level. Generally, a low level is a voltage value with a level of 0 or a small value, and generally cannot achieve the purpose of charging.
It can be seen that there is a problem of low charging efficiency in the encoding method of the prior art
[0003] In addition, in some existing signal transmission technologies, although high level and low level are not used to represent bit 1 or bit 0 encoding, but instead use different time intervals to distinguish different bit values, for example, bit 00 is represented by T+t1, bit 01 is represented by T+t2, bit 10 is represented by T+t3, and bit 11 is represented by T+t4. Using this existing signal transmission technology, the time required to transmit different bit values ​​is longer Long, the encoding efficiency of data bits is low, which increases the burden and cost of the sender and receiver

Embodiment 1

[0050] This embodiment provides a method for sending data, such as figure 1 shown, including:

[0051] Step S101, acquiring a bit sequence of data to be sent.

[0052] Specifically, when the data sender needs to transmit data, it converts the data to be sent into a bit sequence corresponding to the data to be sent by itself or by receiving the data to be sent from the external device, or directly receives the data sent by the external device. The bit sequence of the incoming data to be sent. The data to be sent may be a data frame to be sent by the data sender, and the bit sequence of the data to be sent may include information such as a data frame header, transmission data, and a data frame tail. like figure 2 Shown is an example of a data bit sequence to be sent (that is, a data frame), which includes the data frame header SOF, n bytes of transmission data, and the data frame tail EOF, wherein the data frame header SOF and the data frame tail EOF can be Each communicati...

Embodiment 2

[0120] This embodiment provides a data sending device 80, such as Figure 8 shown. The data sending device 80 is a device corresponding to the data sending method in Embodiment 1, that is, the operations implemented by the data sending party in Embodiment 1 can be specifically implemented by the data sending device 80 in this embodiment. Here, only the structure of the data sending device 80 is briefly described, and for other contents, refer to the description of the data sending method in Embodiment 1. The data sending device 80 of this embodiment includes an acquisition module 801 and a sending module 802, the acquisition module 801 and the sending module 802 can be implemented by one or more processors, wherein:

[0121] The obtaining module 801 is used to obtain the bit sequence of the data to be sent; specifically, the obtaining module 801 can be a separate processor, chip, or a circuit integrated on the processor, and the obtaining module 801 can obtain the data from i...

Abstract

The invention provides a data receiving method and device, wherein the method comprises: detecting a level change of a receiving port; determining N consecutively transmitted waveform sequences according to the level change and the characteristics of the waveform sequences, and determining, according to the N consecutively transmitted waveform sequences, the bit sequence of received data, wherein a first waveform sequence represents either 1 or 0, and a second waveform sequence and a third waveform sequence represent the other one of the 1 and 0 separately. By using the data receiving method, an apparatus can acquire as much electric energy as possible and improve power supply efficiency without affecting data transmission efficiency.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data receiving method and device. Background technique [0002] In the case of wired electrical connection, the sender and the receiver can transmit data through the change of the level, that is, the sender can control the level between the two to control the transmission of the signal. At this time, since there must be a high level between the two, one party can use the high level to charge itself at this time, so as to achieve the purpose of charging while communicating. However, in the prior art, usually high level and low level are directly used to indicate the encoding method of bit 1 or bit 0, that is, when the sender wants to send bit 1, the level on the line remains high; When the sender wants to send a bit 0, the level on this line remains low. At this time, when sending bit 1 or bit 0, there must be a bit represented by a low level. Generally, a low level is a v...
